7、的夹角，上中切牙牙长轴与上前牙牙槽突长轴的夹角，上中切牙牙长轴与鼻底平面的夹角，切牙管前壁线与鼻底平面的夹角，中切牙的长度，中切牙牙根长度，中切牙牙根的直径，唇侧牙槽骨的厚度，腭侧牙槽骨的厚度，切牙牙槽窝底至鼻底平面的距离。采用spss17.0统计软件对所测数据进行统计学处理。结果1．中切牙的长度为22.52±2.38mm2．中切牙牙根长度为11.21±2.21mm3．切牙牙槽窝底至鼻底平面的距离为11.32±2.45mm4.中切牙从釉牙骨质界沿牙长轴向根方4mm、6mm、8mm和10mm处的直径为5.93±2.38m

8、m；5.21±1.48mm；4.65±1.56mm；3.83±2.33mm5.唇侧牙槽骨的厚度从釉牙骨质界向根方4mm、6mm、8mm和10mm处的厚度为0.73±0.31mm；0.83±0.32mm；0.89±0.35mm；0.95±0.37mm6.腭侧牙槽骨的厚度从釉牙骨质界向根方4mm、6mm、8mm和10mm处的厚度为1.
